REST API, webhooks, and native integrations with Shopify, Razorpay, HubSpot, Zoho, Google Sheets, and 40+ more. When something happens in your system, WhatsApp fires automatically.
Send messages, manage contacts, create templates, and trigger bot flows via API. Comprehensive Postman documentation included.
Receive real-time events for every inbound message, delivery status, read receipt, and button click, to any endpoint you choose.
Schedule and send bulk WhatsApp campaigns programmatically via API. Integrate with your existing marketing stack or data pipelines.
Create, submit, and manage WhatsApp message templates via API. Automate your content ops workflow entirely.
The dashboard covers most teams. Developers who want WhatsApp to react to their own systems use the API. Here is the shape of working with it.
Send text, media, templates, and interactive messages. Trigger bot flows. Everything the dashboard can do, your code can do too.
Real-time events for inbound messages, delivery and read status, and button clicks, delivered to any endpoint you choose.
Create, update, tag, and segment contacts from your own application, keeping your CRM and the platform in step.
Submit new templates, check approval status, and manage your library through the API instead of by hand.
Schedule and send bulk campaigns from code, triggered by events in your marketing stack or your own database.
A complete Postman collection means you can try every call before you write a line of integration code.
Meta's Cloud API is available to anyone willing to handle the setup, the template plumbing, the message queueing, the retry logic, and the dashboard to see what is happening. For a team whose product is something other than WhatsApp infrastructure, that is a lot of work to own forever.
The platform API gives you the programmatic control you want while the inbox, CRM, bot builder, and reporting sit ready for the parts you would rather not rebuild. You write the integration that is specific to your business and lean on the platform for everything generic.
Many common connections are pre-built, so check the integrations library before you write custom code.
Trigger visual bot flows from API calls, mixing your code with no-code conversation design.
Drive campaigns from your own events and read the results back through the same API.
The quickest way to understand an API is to see a call. Sending a WhatsApp message comes down to a single authenticated request with the recipient and the content. A simplified example looks like this.
POST /v1/messages
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
{
"to": "919812345678",
"type": "template",
"template": "order_shipped",
"params": { "name": "Priya", "tracking": "BD4471" }
}You authenticate with your key, name the template you already had approved, fill in the variables, and send. The webhook then tells your system when it was delivered and read. The full request and response formats, with working curl examples for every endpoint, are in the API Reference.
Developers weighing their options usually compare building on Meta's Cloud API directly against working through a Business Solution Provider. Both reach the same WhatsApp network. The difference is how much you build yourself.
WA.Expert is a provider that still gives you full API access, so you get the programmatic control of direct integration without rebuilding the inbox, CRM, and reporting that surround it.
